An Accurate Distance to High-Velocity Cloud Complex C
We report an accurate distance of -->d = 10 ? 2.5 kpc to the high-velocity cloud Complex C. Using high signal-to-noise ratio Keck HIRES spectra of two horizontal-branch stars, we have detected Ca IIExpand

THE DISRUPTION AND FUELING OF M33
The disruption of the M33 galaxy is evident from its extended gaseous structure. We present new data from the Galactic Arecibo L-Band Feed Array H I (GALFA-H I) Survey that show the full extent andExpand

A Cold Nearby Cloud inside the Local Bubble
The high-latitude Galactic H I cloud toward the extragalactic radio source 3C 225 is characterized by very narrow 21 cm emission and absorption indicative of a very low H I spin temperature of aboutExpand

The Physical Nature of Neutral Hydrogen Intensity Structure
We investigate the physical properties of structures seen in channel map observations of 21-cm neutral hydrogen (HI) emission. HI intensity maps display prominent linear structures that are wellExpand

GASKAP-The Galactic ASKAP Survey
A survey of the Milky Way disk and the Magellanic System at the wavelengths of the 21-cm atomic hydrogen (H i) line and three 18-cm lines of the OH molecule will be carried out with the AustralianExpand

Ultraviolet Extinction at High Galactic Latitudes II: The Ultraviolet Extinction Function
We present a dust-column--dependent extinction curve parameters for ultraviolet wavelengths at high Galactic latitudes. This extinction function diverges from previous work in that it takes intoExpand

The Accretion of Fuel at the Disk-Halo Interface
We discuss the support for the cooling of gas directly at the disk-halo interface as a mechanism to continually fuel a galaxy. This may be an important reservoir as there is not enough cold gasExpand

HST/COS Observations of Ionized Gas Accretion at the Disk-halo Interface of M33
We report the detection of accreting ionized gas at the disk-halo interface of the nearby galaxy M33. We analyze HST/COS absorption-line spectra of seven ultraviolet-bright stars evenly distributedExpand

Characterizing the Turbulent Properties of the Starless Molecular Cloud MBM?16
We investigate turbulent properties of the non-star-forming, translucent molecular cloud MBM 16 by applying the statistical technique of a two-dimensional spatial power spectrum (SPS) on the neutralExpand

Multi-Messenger Astrophysics: Harnessing the Data Revolution
The past year has witnessed discovery of the first identified counterparts to a gravitational wave transient (GW 170817A) and a very high-energy neutrino (IceCube-170922A). These sourceExpand
